I totally agree. From the observation of myself and my brother, as well as my husband's IQ. The intelligence is 100% from the father's side, not from the mother side.
哈哈,难道聪明的母亲会嫁一个笨丈夫?如果会的话,她还算聪明吗?:)
不应这样理解,孩子的智力,外貌,性格都受父母双方的影响,只是父亲对智力也许还有性格的影响稍多一点而已(比如父亲55%,母亲45%,这只是一个大概的估计,不准确)。
可能说得不清楚。改了一下:
“对于女儿来说,由于她有两条X染色体,一条来源于母亲,一条来源于父亲,母亲贡献基因的优势就荡然无存了。同儿子一样,女儿的大脑也表达更多来源于父亲的基因,所以女儿在智力上就更象父亲。”
